ROOFING MACHINE.

Original application filed May 5, 1913, Serial No. 765,696. Divided and Serial No. 225,963.

To all whom it may comer 1%.

Be it known that we, IIARRY (UMFER and OWEN D. MGFARLANI), both citizens of the United States, residing at Chicago, in the 5 county of Cook and State of Illinois, and Mishawaka, county of St. Joseph, and State of Indiana, respectively, have invented certain new and useful Improvements in Roof-' ing Machines, 1 specification.

This application is a divisional application of an original application filed May 5, 1913, Serial #765696.

Our invention relates to apparatus for of which the following is a of suitable material is coated with 'tar, asphaltum' or other suitable water proofing aterial and finely divided or granular slate, .soap stoneor sand is more or less imbedded in ,the water proofing material and thereby attached to the exposed side of the finished sheet.

The object of our invention is to provide an improved machine for making roofing of the character described in which the granular material may be laid down in patterns using material of various colors or other physical characteristics; to produce a more ornamental and thus a more desirable roof.

To this end, our invention consists in a novel construction, arrangement and com.- bination of parts herein shown and described and more particularly pointed out in the claim.

In the accompanying, drawings:

Fig. 1 is an elevation partly in section of a mechanismadapted for use in the invention.

right angles to Figure 1.

Fig. 3 is a view showing a section finished roofing.

In the construction shown, 1 are rollers or other suitable means'arranged for supporting the coated material 2 preferably arranged to receive the material as it comes from the usual coating machines (not shown). The granular material is fed through a drum 3 provided with pattern openings 4 formed in its peripheral wall.

of the making roofing of that class in which a strip.

Fig. 2 is a section taken substantially at this application filed April 1,

The wall of the drum 3 is preferably finlshed upon the interior. The hopper 5 is positioned within the drum and the portion of the hopper adjacent the openings. 6. In

its bottom snugly fits against the wall of the drum which thus operates as a valve and prevents the escape of material from the hopper except through the opening 6. Any number of pattern cylinders 3 may be -employed to work out the design upon the ro'ofingmaterial by simply positioning the plurallty of hoppers above the roofing sheet.

The pattern cylinder 3 is preferably supported upon a tubular shaft? with suitable openings 8 arranged therein and ri 'dly supported' The hopper 9 is provi ed at its extremities toreceive the granular material and direct the same into the tubular shaft. A rotatable screw conveyor 10, is positioned within the tubular member 7. The drum 3 is rotated by a belt or; chain upon a suit-.

into the hopper 5.. After spaced areas of the sheet have been coated through the first .mentioned drum the remaining areas can be coated by a second drum exactly like the first except that; the perforations, or openings will be offset relative to the openings in the first drumvor the remaining areas can be covered by feeding .the gravel or grit overthe entire surface in the manner shown in the original application of which this is a division.

We claim as our invention:

In a device of the class described, spaced standards, a stationary shaft supported at its ends by said standards, a tubular structure stationarily'supported by said shaft, a tubular stencil rotatably supported at. the periphery of said tubular structure, and means positioned near the end of said structure for imparting movement to said stencil.
